Hi,

You can add your own battery. Please look at the code here:

> <https://github.com/mangOH/mangOH/blob/master/linux_kernel_modules/mangoh/mangoh_yellow.c>

specifically

```auto
static struct bq27426_platform_data mangoh_yellow_battery_gauge_platform_data = {
	.energy_full_design_uwh = 4800000,
	.charge_full_design_uah = 1200000,
	.voltage_min_design_uv = 3300000,
};

```

modify the code to meet your battery requirements., rebuild and deploy on your unit.

@asyal  
yester day i saw this app

> <https://github.com/mangOH/BatteryService/blob/4985ff092d2dbbf42b3c4e5ec39f21eb235111ba/ma_adminbattery.api>

```
/**
 * Configures the battery settings.
 */
//--------------------------------------------------------------------------------------------------
FUNCTION SetTechnology
(
    string type [128] IN, ///< "LiPo" or "LiIon"
    uint32 maH IN, ///< Specify battery current rating as listed by manufacturer
    uint32 voltage IN ///< Specify battery voltage as listed by manufacturer

```

i can change this parameters here?

That SetTechnology function was built for mangOH Red, which couldn’t auto-detect the battery technology. Yellow has a more advanced charger on-board, so it doesn’t implement the SetTechnology function.

Hi,  
following this therd, i want to change the charger current limitation, in the BQ25601 DS i see that need to access to register to increase input current Limit (REG00 IINDPM[4…0] bits) and Fast charge current (REG02 ICHG[5…0] bits).

do have access in 0x6b i2c register to write values on register or only to read it?

BR,
